The start of January not only represents five weeks before the Feb. 8 trade deadline but also three dates on which teams have important roster decisions to make.

Starting on Jan. 5 when teams with open roster spots can sign players to 10-day contracts to Jan. 7 when non-guaranteed contracts become guaranteed and ending on Jan. 15 -- the last date to sign a player to a two-way contract -- general managers will have their personnel department on speed dial.

We go team by team, breaking down the impending roster decisions, implications and likely outcomes.
